What's with all the old-a** anime suggestions (and no one mentioning Baka to Test or Yosuga no Sora, both definently good harems, and unique in there own ways), makes me think you may be talking about the dubbed versions (DUBS = Americanized cartoons). Anyway, if you are looking for recent harem anime, crunchroll has a few of good ones:

There are many others, but I can't really say which is the best because the plots very so greatly. Anyway, all the above are worth watching (Don't watch Yosuga no Sora or Kiss X Sis with kids in the room), and most have lots of comedy them.
